4IMPROVEMENT IN sKATEs.

` VSpecification forming part of Letters Patent No. 36,819, dated October 28, 1862.

To all whom it may concern:

Beit known that I, SAMUEL G.. CRANE, of Rochester, in the county of Monroe and State of New York, haverinyented an Improved Fastening for Skate-Woods; and I do hereby I declare that the following is a full, clear, and

exact description thereof, reference being had to the annexed drawings, making apart of this specication, in which- Figure 1 is 'a side elevation of the skate. Fig. 2 is a section taken through the collar C,

foot-piece B, and nut c in the directionof the, red line-o in Fig. 3. Fig. 3 is a transverse;

section through the plane indicated by the red lines o in Figs. land 2.' Fig. Llis abottom view of the collar C.- Figs.` 2, 3,' and 4 are enf larged views,being full size. l

Similar letters of` reference indicate corresponding parts in the several figures..

The nature'of` this invention will be understood by reference to the drawings and speciication.

A To enable others to make and use my invention', I will proceedto describe its construction, 8vo.

" The runner-plates D are cut from bars rolled with one edge thick 'and the otherfthin,as seen in-Fig. 3, 4whereby they require uo forging inV their Inanufactureexcept to give them the desired curvature; The nicks a, for the footstraps to pass through, are punchedout, as are also the recesses in which the Abody and t head ofthe screws s and s are fitted, and in which the bodies of the collars C are placed, as seen in Fig. 2. Said collars C may be shaped externally as shown in the drawings, or in any other desired form, and they are cast'with -agroove`,`j`f, Fig. 4, running across the lower face; to correspond to the thickness of the runnerf at that'point', 'and there is also'a notch, z', at each'end ofthefgroove, running through to the upper face of the collar, thus leaving the body or solid portion of it rectangular, as seen in Fig. 2, the screw-hole passing through the center, as seen in Fig. 4'.l The foot-piece B is shaped to conform to the curve `of\the upper edge of the runner-D,l and it is bored to lit the round portion of the body of thescrews s and s', and .also to receive thel nuts c. The runner D is let into the toc 0f the foot-piece, as indicated by the red line g, Fig. l. The screws s and s are placed in their position in the ruuner D, where the heads are .held by the projections e, Fig 2. The collars C are then turned with the groove f parallel with the-runner and slipped on' over the screws, and those I portions forming the sides of the grooves, as indicated by the dotted lines in Fig. 2, clamp the upper edge of the runner, and whenl the foot-'piece is secured in position by the nuts c the parts are all firmly and securely connected together. The screws s and s have that portionnithe body next the head between the projections e :made square, as seen" in Figs. 2 and 3, whicheectually prevents their turning when the nut-s c are screwed on or off, and

also prevents the screw s from turning when the heel-spur h, which `is a continuation ol' the said screw, is being attached to or' removed froni thebootwhich is an important item. It will be seen that the collars C act as lateral bracesor supports to thefoot-piece B, to en-` able it to resisl4 side thrusts or strains against the lower edge of therunner D, causing said strains to center in the screws s and s and the collars C, instead of in the 'foot-piece at the point of contact with therunner D, as in the ordinary construction of this class of skates,

and by clutching the screw-heads to the pro- 3 jections e at a point so much below the -footscribed and is placed' entirely below the lowerv face of the foot-piece, in the manner and `for purposes specified.
